I'm sorry but I can't support attachment problems related to SMF to SimplePress migration.

In any case if you fixed this issue you should first install wpForo before installing Go2wpForo tool and starting migration. Go2wpForo tool migrates SimplePress attachments without any issue.

Many thanks @robert for this info.

So if I have a SimplePress Forum with working attachments, so e.g. that a posted picture is shown

embeded inside the posting in SimplePress, the Go2wpForo tool will also convert it to WPForo ?

Where are picture attachments stored in WPForo ? In den Wordpress Media Library or in a different path ?

Many thanks. Regards, Stefan

rather than opening a new topic I am adding another question here:

I am currently trying to convert my SimpleMachines SMF forum to WPFORO

via the way to first convert it to SimplePress and then from SimplePress to WPForo.

Now my question is: I have already suceeded in converting SMF to SimplePress

with the sp-importer Plugin from SimplePress, but the attachments do

not show up in SimplePress...

Do I need to order first a few plugins for the attachments to show up or does the

sp-importer Plugin not support any attachments ?

Is there somewhere a good documentation how to do this inclusive attachments ?

2. If I have got the forum to run under SimplePress including attachments

how do I then convert from SimplePress to WPFORO with this Converter Program ?

Need I to install first WPFORO also in my Wordpress to do this and then run the converter

or do I need to run it without installing WPFORO first ?

A bit more FAQs about the converter plugin would be really appreciated.

Many thanks.

Regards, Stefan.

As per database size, I can only say all are your data, wpForo only generates as extra data post titles (most forums don't have post titles, only topic titles). So 37k titles for 37k post should increase posts table size. Other tables are very close. And as I've already mentioned above there is no mean to compare two totally different database architectures. wpForo may have 20 fields, SF 10 fields in the same table....

Also if you want to increase forum speed you should use the Simplified layout. Now you use Extended layout, it loads recent topics on forum page and recent posts on topic page. With the extended layout forum looks very busy and active, it invites people to forum. Forum visitors read and join to forum very easy. It's very good for engagement but it's bit slow than the Simplified layout, because you display dozens of times more information on the same page (recent topics and recent posts).

Another option to speed-up forum is decreasing recent topic and posts counts to 2-3. Currently it's set 5.

Not only those tables in the image. The original SimplePress DB is lower in size in comparision with the new migrated DB of wpForo. This may concerned that migration process is not properly done, by the migration system. I do not know, But the result is that.

I don't understand what you mean with "your website URL wpForo is totally crashed and it doesn't work correctly". I'm looking at the error.log, and I see no problem in WordPress or the wpForo plugin. In all the tests I've done, wpForo works. Several members of our staff are tested too, and some readers. The conclusion of all is that it works, but speed is the big problem. 

It would be nice to have some tool to check the DB structure finding issues. My interest is migrate to wpForo. Perhaps adjusting the cache, speed improves. I liked the plugin and I think you have done a good job, and there is much to do, but I must solve these problems, so I appreciate your help.

As far as I see after clicking on your website URL wpForo is totally crashed and it doesn't work correctly, so it may work slow. The correct way to test/compare speed and performance is using both forums on fresh WP installation. Also you should make sure the database doesn't have incorrect things. Maybe wpForo table indexes are damaged or removed. We don't know how the migration was completed.  And the table and index statuses are also not clear here.

Please don't review forum platform and performance based on migrated database. Forum will always work faster and correct if it inserts all data in regular use, from fresh installation time-point.

I lost some posts in the conversion, but it is no problem.
